I have missed this news about BAT, but will read it from your link..
As third comment, I am using third type of Brave... for Linux.. :)
It has some issues with videos and flash (CPU load gets high), but that is common problem for all browsers. I was using Firefox for years, but in need for Tronlink, Keychain and other plugins, I have to use Chrome in that case... so, Brave come as ideal solution, as it has both things... It looks like FF and works as Chrome... :)

Anyway, if you have problems with viewing some pages, if you turn off shields, they can work sometimes... but, that is a risk, I know...

Cheers!
